The back Wall 11 has a recess 15 therein for the passage of a driving pulley 17 on the reel shaft 18. The driving pulley,- andits appurtenances, are protected against injury by the recess '15.

e it [known that I, LLOYD BROWN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and usezine Attachments for which the following is a specification.

This invention relates to magazines for holding films for kinetographs and relates Kinetographs, of

One end and a circular side wall 12. ,The front of wall at 33 of this recess is an overhanging the case has a circular opening for insen wall, and the end of the base 30 1S adapted Will fully protect thefilm an improved attaching or be automatically 21 is slipped over the member 20 and has I screw threaded at 14 into the.

Block 46 is stationary and basez in the position indicated; while block to be slipped in under the overhanging wall, so that when the base is in the position shown in Figs. 2 and 3, that end of the base is held down by the overhanging wall. At the other end of the recess the wall 34 is straight; so that the other end of the base may be set down into the recess. This other end ot' the base is then held in place by means of a screw 35 which screws up into a bushing 36 set in the base 30. The base and the case are, in this particular instance, made of cast aluminum and it is therefore desirable to place a bushing 36 of brass or other suitable material in the cast aluminum to carry the thread. The screw 35 has a large head 37 on its lower end. The screw projects through the wall 32 of the kinetograph mechanism, the head 37 being on the inside of the mechanism; and the screw is yieldingly pressed upwardly by a spring 38 held in a small housing 39. The spring pressing the screw upwardly facilitates the screwing of the screw upwardly into the screw-threaded bushing 36; and at the same time the spring allows the upper end of the screw 35 to be pushed downwardly when the magazine is first put in place so that the screw will be automatically set ready for manual manipulation when the parts are as sembled.

It will be noted that both ends of the base 30 are similarly constructed; and in the other end of the base there is also the same screw-threaded bushing 36. This provision is made so that the same magazine may be used either for the top or for the bottom of a camera mechanism in a situation where both magazines have their cover plate 13 turned toward the same side and where the two screws 35 (the one for the upper magazine and the one for the lower magazine) are both at the same face of the camera.

The film F comes out of or goes into the magazine over a roller 45 and through a slot formed between two blocks 46 and 47. is secured in the 47 is movable toward block 46. Block 47 has a large flat fiange 48 which is movable in a recess 49 in the bottom of the base. The flange 48 is held up against the bottom of the base by headed screws 50 which play in slots 51 in flange 48; and the flange 48, with its block 47 are pressed toward block 46 by a suitable fiat spring 52. Normally this spring 52 presses the block 47 toward the block 46 so as to tightly grip the film between the felt facings 46 and 47 a of the two blocks. When, however, the magazine is put into position as shown in Figs. 2 and 3, then the bevelled surfaces 53 of a pair of pins 54 entering a pair of apertures 55 in flange 48 press that flange and its block 47 back away from block 46 to a sufficient extent to take the pressure of! the film, yet

not to a suflicient extent to open up wide the slot between the two blocks. Thus, when the magazine is in place, then the opening between the two blocks is opened up sufiiciently to allow the film to pass more or less freely out of or into the magazine, and yet the space is not large enough to allow any appreciable filtering of light therethrough. The film also passes between two walls 60 upon entering the interior of the camera case. These walls are faced at 61 with felt or the like; and the bottom of the recess 31 is likewise faced with felt as shown at 62. The slot at 63, through which the film passes between the walls 60, is just wide enough to allow free passage of the film without any substantial leakage of light.

At the end toward the opening 16, through which the driving means for pulley 15 pass to the interior of the case and to the drive mechanism contained therein, light is prevented from entering between the ends of the blocks 47 and 46 by a plate against which the ends of the blocks abut. The other end of the slot between the blocks is of course protected by the wall 31 of the recess 31.

Having described a preferred form of my invention, I claim:

1. The combination of a kinetograph case having a magazine seat with a film passage therethrough, a film magazine having a film passage to register with the passage in said seat, a sliding member housed between said magazine and case and forming a movable wall for said magazine film passage, means automatically to slide said member when said case and magazine are assembled and the film passages brought into registry, and means for fastening said magazine and case in assembled position.
